Usage Guidelines

Usage Scenario

At the beginning of the AMB/SMB switchover, an RSVP-TE GR node enters a period during which the data plane can forward data but the control plane is not restored. A Restart timer starts following this phase. The restart time is relevant to the basic time, the number of ingress LSPs and the number of non-ingress LSPs. The default basic time is 90 seconds. You can use the mpls rsvp-te hello basic-restart-time command to change the value of the basic time.

After the Restart timer expires, the node starts a Recovery timer. The recovery time is relevant to the restart time and total number of LSPs.

Prerequisites

RSVP GR has been enabled by running the mpls rsvp-te hello full-gr command in the MPLS view.

Example

# Set the basic time of RSVP GR to 39 seconds.
